Barsauma

Barsauma (418-490) was Patriarch of the East from 484 to 485, succeeding Babowai and preceding Acacius of Seleucia-Ctesiphon. He was the first Nestorian patriarch.

Biography
Barsauma worked as a teacher at the School of Edessa, where he was mentored by Bishop Ibas of Edessa. He and Ibas were excommunicated for their Nestorian theology following the First Council of Ephesus in 431, but he became metropolitan of Nisibis and became a favorite of Shah Peroz I. In 484, he had his rival Babowai executed by Shah Peroz, and he was known to discipline his bishops. In 485, he was deposed and replaced by Acacius of Seleucia-Ctesiphon, and he returned to being metropolitan of Nisibis. He later reopened the School of Nisibis, which became the center for Nestorianism in the East; he died in 490.
